Really liked this chapter.
This is definitely the kind of thing that Harry might have thought about later in life.
I like the recognition of McGonagall.
Also you put Harry and Ginny's relationship well

I love how all of these things don;t really go together but it all works. It goes through the smallest moments which have a big impact in this story. My favorite was Sherbet Lemons, which turned out great like the rest of the story. Great job!
